摘要:

乳腺癌的进展可以在淋巴结全载玻片图像(WSIs)中量化。我们描述了一种新的方法,有效地进行分类的全载玻片图像和患者水平的乳腺癌分级。我们的方法利用了深度神经网络。该方法对小块进行分类,并使用模型平均进行提升。在第一步中,感兴趣区域的补丁被确定和裁剪自动颜色阈值,然后由深层神经网络分类。分类结果用于确定载玻片级别类别,并用于进一步聚合以预测患者级别等级。我们的方法的快速处理速度使得高通量图像分析成为可能。

英文摘要:

The progression of breast cancer can be quantified in lymph node whole-slide images (WSIs). We describe a novel method for effectively performing classification of whole-slide images and patient level breast cancer grading. Our method utilises a deep neural network. The method performs classification on small patches and uses model averaging for boosting. In the first step, region of interest patches are determined and cropped automatically by color thresholding and then classified by the deep neural network. The classification results are used to determine a slide level class and for further aggregation to predict a patient level grade. Fast processing speed of our method enables high throughput image analysis.
